PH is a measure of how acidic/basic water is. The range goes from 0 to 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base. The pH of water is a very important measurement concerning water quality.
The atomic number of iron, Fe, is 26. This means it has 26 electrons.
Now, as we write the configuration, we come up to electronic subshell 3p, which is completely filled. So the configuration up till this point is identical to Argon, so we may write:
[Ar], 3d, 4s
After the electrons in the Ar configuration are accommodated, there are 8 electrons left for the 3d and 4s shells. The 4s subshell, when empty, is at a lower level than the 3d level, so it fills first. Two electrons are placed here. Therefore, 3d has 6 electrons in Fe.
Answer:
B, carbon dioxide
Explanation:
It is released through many human activities such as burning fossil fuels, deforestation, land use, and even respiration.
Answer:
28
Explanation:
electron = atomic number - charge(if the charge is positive and addition if the charge is negative)
electron = 30 - 2
electron = 28
